Google Merchant Center is where an online shop’s product data has to live before Google will show those products in Shopping results, Performance Max or the free product listings. I set up Merchant Center accounts for UK online retailers, connect the product feed, and clear the disapprovals and warnings that keep products out of the auction. The aim is a feed Google accepts, that matches what your website actually says, and that gives your campaigns enough detail to bid sensibly.
Why the feed matters more than the campaign
Shopping ads have no keywords. When someone searches for “women’s waterproof walking boots size 6”, Google decides which products to show by reading your feed: the title, description, product category, brand, barcode number and price. A product feed with vague titles and gaps in its attributes gets matched to fewer searches, and often to the wrong ones. No bid change inside the campaign can repair that.
The feed also decides whether a product is allowed to appear at all. Merchant Center checks every item against Google’s shopping policies and its data requirements. A feed price that differs from the product page, a missing delivery cost or an image with a sale banner across it can each stop an item. Problems with the website as a whole, such as a thin returns policy or hard-to-find contact details, can suspend the entire account.
Who this suits, and who it does not
It usually suits:
- Shops starting Google Shopping or Performance Max campaigns for the first time, which need Merchant Center configured properly before any budget is spent.
- Retailers with products stuck as disapproved or showing limited performance, or an account suspended for misrepresentation, who need the cause found and dealt with.
- Shops with large or fast-changing catalogues, where prices, stock levels and sale dates move often and the feed drifts out of step with the site.
It suits less well if you sell a handful of products and your platform’s own Google app already sends a clean feed. Then the job is a short check rather than a project, and I will tell you so. It is also the wrong fix when the problem is the campaign rather than the data: weak bidding, a poor budget split or tracking that does not record sales. That belongs in ongoing PPC management.
What feed management covers
Merchant Center setup
I create or tidy the Google Merchant Center account, verify and claim the website, and enter the business details Google shows to shoppers. Delivery costs, delivery times and the returns policy are set for the UK inside Merchant Center rather than left for Google to guess, because missing or inaccurate delivery information is a common reason for warnings on a new account. Then I link Merchant Center to Google Ads and, where it is useful, to Google Analytics.
Choosing the feed source
Most UK shops run on Shopify, WooCommerce, BigCommerce, Magento or a bespoke build, and each sends products to Google differently: an official app or plugin, a scheduled file, a Google Sheet, or Google’s API for larger catalogues. I choose the route that keeps the data accurate with the least manual effort, and I check how often it refreshes. A feed that updates once overnight can still be showing yesterday’s price at four in the afternoon.
Titles, descriptions and attributes
Titles carry more weight than anything else in the feed. I rewrite them so the words a buyer types come first: brand, product type, then whichever attributes matter in that category, such as size, colour, material or pack quantity. I also complete the GTIN (the manufacturer’s barcode number) where one exists, the Google product category, product type and condition, and the variant attributes that turn each size and colour into its own item.
Supplemental feeds and feed rules
Many shop platforms cannot store every attribute Google asks for, or they overwrite manual edits each time they sync. A supplemental feed adds or corrects attributes alongside the main feed without touching the shop’s database, and feed rules change values as they arrive, for example putting the brand at the start of every title in one range. Fixes made this way stay in place when the platform resyncs.
Custom labels
Google gives every product five custom labels to tag it however your campaigns need. I normally fill them from your own figures: margin band, best sellers, seasonal lines, clearance stock or price range. That lets campaigns push harder on products that make money and hold back on those that only add turnover.
Disapprovals, warnings and suspensions
I work through the Merchant Center diagnostics item by item, separate data errors from policy problems, and fix the cause rather than hiding the symptom. For an account-level suspension, usually for misrepresentation, that means reviewing the site the way Google’s reviewers do: delivery and returns pages, contact details, checkout and payment, and any claims made on product pages. I only request a review once the site has genuinely changed, because after repeated unsuccessful requests Google can make you wait before trying again.
Free listings and promotions
Once the feed is clean, the same data can work harder. Free listings put products in the Shopping tab and other Google surfaces with no charge per click. Merchant promotions add an offer note to eligible products. Retailers with physical shops can also show local stock to nearby searchers, which needs a separate local inventory feed and a linked Google Business Profile.
How a feed project runs
- Access and audit. You add me as a user on Merchant Center, Google Ads and your shop platform, so no password is ever shared. I export the diagnostics, compare a sample of products with their live pages, and list every error, warning and missed opportunity.
- Priorities. I rank the fixes by how much revenue they return to the auction, starting with disapproved best sellers and anything that puts the account at risk.
- Fixes at the source. Wherever I can, I correct the data in the shop or its feed app so the change lasts. Supplemental feeds and rules cover what the platform cannot hold.
- Titles and attributes. Category by category, starting with the products that already sell.
- Checks after reprocessing. Merchant Center can take a few days to review changed items, so I confirm approval status once that has happened, not on the day of the edit.
Feed problems I see most often on UK shops
- Prices without VAT, or prices that do not match the page. UK feed prices must include VAT and agree with what the shopper sees on landing. A sale that ends on the site but not in the feed causes the same error.
- Delivery charges missing or wrong. Free delivery thresholds, surcharges for the Highlands and Islands, and different courier options are often not reflected in Merchant Center.
- Titles copied straight from the shop. Short, branded product names read well on the site and tell a searcher almost nothing.
- Missing barcodes on branded goods, which limits how products are matched to searches.
- Variants sent as a single product, so the shopper lands on the wrong size or colour.
- Thin returns and contact pages that leave the whole account exposed to a misrepresentation suspension.
Accurate product markup on the website helps with several of these. When product pages carry correct price and availability data, Merchant Center can update items automatically and mismatches surface sooner, so structured data implementation and feed work tend to support each other.
What you receive
- A written audit of the feed and account, with each issue ranked and its cause explained.
- A Merchant Center account linked to Google Ads, set up for UK delivery and returns, and cleared of every error that was in my power to fix.
- Rewritten titles and completed attributes for the product categories we agreed.
- Documented supplemental feeds and rules, so whoever looks after the shop next knows they exist.
- A short note on anything I could not fix and why, such as products Google does not allow at all.
Next step
Send me your shop’s address and tell me what Merchant Center is showing you, or that you are starting from nothing. I will say whether it needs a project or a handful of fixes. Feed work is quoted after I have seen the account, in GBP, and the quote is agreed in writing before work starts. Once the feed is sound, the campaigns that rely on it can be run as part of my Google Ads services. To start, book a consultation.
